Abstract

Municipal garbage and seaweed are organic materials which can be soil ameliorant (additive) important to improve soil chemical and physics. Different organic material sources given to the soil will make plants growing on it respond differently except the seeds. This study aim at testing the response given by organic matter from the city garbage and seaweed on marginal soils (with low pH areas, clayey texture and low nutrient content) on the jackfruit seed growth. The research design used is random complete design with 6 treatments and 4 replications. The treatments tested were B0 = (control-without ameliorant), B1 = Soil + (100 mg N, 60 mg P, 100 mg K, 60 mg Mg, Ca 60 mg kg -1 soil)., B2 = Soil + (50 mg N, 30 mg P, 50 mg K, 30 mg Mg, 30 Ca mg kg -1 soil) + organic materials. Sea weed., B3 = Soil + organic materials. Seaweed., B4 = Soil + (50 mg N, 30 mg P, 50 mg K, 30 mg Mg, 30 mg Ca kg -1 soil) + organic materials. Municipal garbage., B5 = Soil + organic materials. municipal garbage. The results showed that the provision of municipal garbage organic and seaweed significantly affect the parameters of leaf width, however, sea weed organic materials has a more significant effect than  municipal garbage.

Abstract

Pertambangan emas yang menggunakan metode arsenik dan merkuri dalam proses pemurnian akan selalu menimbulkan dampak lingkungan. Sisa tanah hasil penambangan (tailing) akan dibuang atau didepositkan, dan akan menimbulkan masalah lingkungan dan juga mencemari pangan. Tanaman yang ditumbuhkan pada lahan terkontaminasi dapat bersifat adaptif terhadap kontaminan tetapi tidak mentranslokasikan, ataupun bersifat adaptif dan mentranslokasikan dengan dan tanpa translokasi kontaminan. Penelitian ini bertujuan untuk menguji sifat adaptif/toleran Sawi dan Tomat jika ditanam pada tanah tercemar merkuri dan juga kemampuan translokasi merkuri. Total 6 perlakuan dengan 3 kali pengulangan ditentukan untuk setiap jenis tanaman supaya dapat menarik kesimpulan penelitian, seperti perlakuan tanah tailing saja, tanah tailing campur pupuk (100 mg N, 50 mg P, dan 50 mg K),  tanah tailing dengan kotoran ayam, tanah tailing dengan campuran rumput laut, tanah tailing dengan dosis pupuk rendah (50 mg N, 25 mg P dan 25 mg K), dan tanah non tailing yang dicampur pupuk N,P,K dosis rendah. Untuk sawi dan tomat digunakan masing-masing 18 unit percobaan untuk tomat.  Dosis rumput laut maupun kotoran ayam adalah 5g kering angin kg-1 tanah. Statistik mengunakan analisa Anova 1 arah dengan uji lanjut BNJ. Sawi yang tumbuh pada tanah tailing terkontaminasi 85.700 ηg g-1 mentranslokasikan Hg hingga 17.477 ηg g-1 dan hanya 6.281 ηg g-1 pada tomat.  Efisiensi Sawi sangat tinggi untuk membersihkan kontaminan Hg, minimal 68 kali lebih efisien dari tomat. Pemberian N, P, K pada tanah tailing berkontribusi negatif pada pertumbuhan tanaman berbeda dengan pemberian bahan organik asal kotoran ayam yang memberikan kontribusi positif pada pertumbuhan sawi maupun tomat, juga menurunkan  penyerapan Hg.

Abstract

A quite big amount of tomato for consumption in Indonesia is still from import. There are two strong challenges on tomato production namely low productivity and pest and diseases. The challenge to improve tomato production becomes stronger if it is planted on acid soil. Acid soil is well known to have low pH which influence on the macro nutrients availability such as N and P.  This experiment was aimed to investigate the effectiveness of Pseudomonas sp on tomato growth and P uptake on acid soil. There were 8 treatments tested namely control treatment non-sterilized soil; control sterilized soil;non-sterilized soil + Pseudomonas sp;sterilized soil +Pseudomonas sp;non-sterilized soil + Pseudomonas sp + N, P, K; sterilized soil +Pseudomonas sp + N, P,K; non-sterilized soil + N, P,K ; sterilized soil + N, P, K; and treatment was replicated 3 times. The data was then analyzed with One Way ANOVA and tested by Tukey HSD. Bacteria Pseudomonas sp amendment increased significantly Phosphor (P) concentration, uptake in the shoot of tomato, and triggered the flowering. Amendment of low concentration of N, P, K, together with Pseudomonas sp on acid soil improved significantly tomato growth (plant height, and shoot and root dry biomass), leaf chlorophyll concentration and soil bacteria total colony. The effectiveness of Pseudomonas sp on plant growth was strongly improved when the acid soil microbe diversity was maintained (non-sterilized soil).

Abstract

The purpose of this study was to evaluate the plant growth performance of top grafted young cacao cultivated in various elevations. This research was conducted from January-August 2019 in South Sulawesi and Central Sulawesi. A total of 54 plants were taken randomly from 6 locations with 3 altitudes (<300, 300-600, >600 meter above sea level, as.). The results showed that there was not significant different of plant height, stem circle, crown circle, the number of primary branches, the number of flowers, the length of horizontal and vertical roots in response to different elevations. However, the height of primary stem and leaves number of cacao from <300 m asl was significantly greater than those from either 300-600 m asl or > 600 m asl. The largest crown portion of actual biomass was found in the branches, then followed by the leaves and stem. While the highest actual root biomass was found at 10-20 cm soil depth.

Abstract

Root and soil interactions will alter the biochemical status of the rhizosphere, the acquisition of nutrients and impacted to plant growth. The biochemical of the rhizosphere is strongly influenced by the agriculture input e.g. fertilizer, herbicides and farm management system. Application of fertilizers, their effects are robust and difficult tobe quantified. The effect of fertilizer on the biochemical status rhizosphere and plant growth is different depending on the type of fertilizers, growth media, plant species, and also the environment condition, while the effect on plants will be specific to each plant. This research investigated on the effect of N inorganic fertilizer inputs from two sources namely Urea (CO(NH2)2) and Ammonium Sulfate or ZA ((NH4)2.SO4), and different fertilization method (homogenous and localized). Experiments showed application of N-Urea and N-ZA fertilizers reduced the rhizosphere pH until 1,4 point. However, acidity of the rhizosphere reduced microorganism colonies and respiration rate.

Abstract

The performance of the Wastewater Treatment Plants (WWTP) in several hospitals is reported low, where the wastewater often does not meet the quality standards so that it has the opportunity to pollute the environment. Horizontal Sub-surface Flow Constructed Wetland (HSSF-CW) is a green and sustainable technology; it can be used as an alternative technology for hospital wastewater treatment. This study aimed to evaluate the performance of HSSF-CW on a pilot-scale in the removal of total coliform (TC) and total suspended solids (TSS), as well as to assess the effect of Ludwigia adscendens, Echinodorus paniculatus, and Typha angustifolia plants on the performance of HSSF-CW using experimental methods. The operational and design strategy adopted was setting the water depth at 0.30 m, maximum hydraulic loading rate of 3.375 m3/day, continuous wastewater recirculation, the use of river sand-gravel media measuring 5–8 mm, as well as setting tight spacing for T. Angustifolia was 53 clumps per m2, L. adscendens 133 stems per m2, and E. paniculatus 13 clumps per m2. The results of this study indicate that the performance of the HSSF-CW system on a pilot-scale planted with L. adscendens, E. paniculatus, or T. Angustifolia has proven to be able to eliminate the TC and TSS parameters of hospital wastewater to match their respective quality standards in hydraulic retention times <2 and 4 days. It can be concluded that T. Angustifolia, E. paniculatus, and L. adscendens positively boost the performance of HSSF-CW in the removal of TC and TSS. However, T. Angustifolia had a better effect than E. paniculatus and L. adscendens on the performance of the HSSF-CW system. Keywords: Constructed wetland, E. paniculatus, Hospital wastewater, L. adscendens, T. angustifolia ABSTRAK Kinerja Instalasi Pengolahan Air Limbah (IPAL) beberapa rumah sakit dilaporkan rendah, dimana air buangannya seringkali tidak memenuhi baku mutu sehingga berpeluang mencemari lingkungan. Horizontal Sub-surface Flow Constructed Wetland (HSSF-CW) adalah teknologi hijau dan berkelanjutan, yang dapat digunakan sebagai teknologi alternatif untuk pengolahan air limbah rumah sakit. Penelitian ini bertujuan untuk mengevaluasi kinerja HSSF-CW skala percontohan dalam penghilangan total coliform (TC) dan total padatan tersuspensi (TSS), serta menilai pengaruh tumbuhan Ludwigia adscendens, Echinodorus paniculatus, dan Typha angustifolia terhadap kinerja HSSF-CW dengan metode eksperimental. Desain dan strategi operasional yang ditempuh adalah pengaturan kedalaman air pada 0,30 m, laju pemuatan hidrolik maksimal 3,375 m3/hari, resirkulasi air limbah secara kontinyu, pemakaian media pasir-kerikil sungai ukuran 5–8 mm, serta pengaturan jarak tanam yang rapat masing-masing untuk T. angustifolia adalah 53 rumpun per m2, L. adscendens 133 batang per m2, dan E. paniculatus 13 rumpun per m2. Hasil penelitian ini menunjukkan bahwa kinerja sistem HSSF-CW skala percontohan yang ditanami L. adscendens, E. paniculatus, ataupun T. angustifolia terbukti mampu menyisihkan parameter TC dan TSS air limbah rumah sakit hingga sesuai baku mutu dalam waktu retensi hidrolik <2 dan 4 hari. Dapat disimpulkan bahwa T. angustifolia, E. paniculatus, dan L. adscendens secara positif mendorong kinerja HSSF-CW dalam penghilangan TC dan TSS. Namun, T. angustifolia memiliki pengaruh lebih baik dibandingkan E. paniculatus dan L. adscendens terhadap kinerja sistem HSSF-CW.
